RESUMO

Fracture of the alveolar bone resorption is a common complication in orthodontic treatment, which mainly caused by extreme mechanical loading. However, the ferroptosis with orthodontic tooth movement(OTM) relationship has not been thoroughly described. We here analysed whether ferroptosis is involved in OTM-associated alveolar bone loss. Mouse osteoblasts (MC-3T3) and knockdown glutathione peroxidase 4 (GPX4) MC-3T3 were stimulated with compressive force loading and ferrostatin-1 (Fer-1, a ferroptosis inhibitor), and the changes in lipid peroxidation morphology, expression of ferroptosis-related factors and osteogenesis levels were detected. After establishing the rat experimental OTM model, the changes in ferroptosis-related factors and osteogenesis levels were reevaluated in the same manner. Ferroptosis was involved in mechanical stress regulating osteoblast remodelling, and Fer-1 and erastin affected osteoblasts under compression force loading. Fer-1 regulated ferroptosis and autophagy in MC-3T3 and promoted bone proliferation. GPX4-dependent ferroptosis stimulated the YAP (homologous oncoproteins Yes-associated protein) pathway, and GPX4 promoted ferroptosis via the YAP-TEAD (transcriptional enhanced associate domain) signal pathway under mechanical compression force. The in vivo experiment results were consistent with the in vitro experiment results. Ferroptosis transpires during the motion of orthodontic teeth, with compression force side occurring earlier than stretch side within 4 h. GPX4 plays an important role in alveolar bone loss, while Fer-1 can inhibit the compression force-side alveolar bone loss. GPX4's Hippo-YAP pathway is activated by the lack of compression force in the lateral alveolar bone.

RESUMO

OBJECTIVE: To evaluate the economic value of mepolizumab as an add-on therapy to the standard of care (SoC) for patients with severe eosinophilic asthma in China. METHODS: A Markov model with three health conditions was constructed to calculate the incremental cost per quality-adjusted life year (QALY) in mepolizumab with SoC and SoC only groups from the perspective of the Chinese healthcare system throughout an entire lifespan. The model was populated with local costs, while efficacy parameters were obtained from the global Phase III MENSA trial and mortality was derived from two surveys. One-way and probabilistic sensitivity analyses were conducted. Additional scenario analysis was used to estimate the cost-effectiveness impact of changes in the price of mepolizumab. RESULTS: Over the lifetime treatment horizon, the incremental cost-effectiveness ratio (ICER) of mepolizumab plus SoC compared to SoC alone was $170 648.73 per QALY. Sensitivity analyses focused on these results. Scenario analysis showed that mepolizumab would require a price reduction of at least 82% to reach the current willingness-to-pay (WTP=$38 223.34/QALY) threshold. CONCLUSION: Mepolizumab is not a cost-effective healthcare resource in China at its current pricing.

RESUMO

BACKGROUND: Erectile dysfunction (ED), defined as the inability to achieve or maintain a penile erection sufficient to satisfy sexual behavior, is prevalent worldwide. AIM: Using previous research, bioinformatics, and experimental confirmation, we aimed to discover genes that contribute to ED through regulating hypoxia in corpus cavernosum smooth muscle cells (CCSMCs). METHODS: We used the Gene Expression Omnibus to acquire the sequencing data of the corpus cavernosum transcriptome for diabetic ED and nerve injury type ED rats. We intersected the common differentially expressed genes. Further verification was performed using single cell sequencing. Real-time quantitative polymerase chain reaction and immunofluorescence were used to investigate whether the differentially expressed genes are found in the corpus cavernosum. We used induced hypoxia to assess cell viability changes, and we developed a lentivirus overexpressing Cldn4 for in vitro and in vivo experiments to measure changes in JNK signaling, fibrosis, hypoxia, and erectile function. OUTCOMES: Our results indicate that targeting the JNK pathway and decreasing local hypoxia may be better options for therapeutic intervention to improve erectile function. RESULTS: We identified Cldn4 and found its expression increased in the corpora cavernosa of the 2 datasets. In addition, we found that hypoxia can increase the expression of Cldn4, activate the JNK signaling pathway, and exacerbate fibrosis in CCSMCs. Cldn4 overexpression in CCSMCs activated the JNK signaling pathway and increased fibrotic protein expression. Last, rat corpus cavernosum overexpressing Cldn4 activated the JNK signaling pathway, increased local fibrosis, and impaired erectile function. CLINICAL IMPLICATIONS: Through bioinformatics and in vitro and in vivo experiments, we found that Cldn4 has a negative effect on ED, and targeting Cldn4 may provide new ideas for ED treatment. STRENGTHS AND LIMITATIONS: Although we have identified Cldn4 as a potential target for ED treatment, we have only conducted preliminary validation on CCMSCs, and we still need to further validate in other cell lines. CONCLUSION: CCSMC hypoxia leads to increased Cldn4, in both nerve injury and diabetic ED rat models, and promotes fibrosis by activating the JNK signaling pathway.

RESUMO

Squamous cell carcinoma of the head and neck (SCCHN) is a commonly detected cancer worldwide. Human papillomavirus (HPV) is emerging as an important risk factor affecting SCCHN prognosis. Therefore, identification of HPV status is essential for effective therapies in SCCHN. The aim of this study was to investigate the prognostic value of HPV-associated RNA biomarkers for SCCHN. The clinical data, survival data, and RNA-seq data of SCCHN were downloaded from The Cancer Genome Atlas database. Before the differential expression analysis, the heterogeneity between the 2 groups (HPV+ vs HPV-) of samples was analyzed using principal component analysis. The differentially expressed genes (DEGs) between HPV+ and HPV- SCCHN samples were analyzed using the R edgeR package. The Gene Ontology functional annotations, including biological process, molecular function and cellular component (CC), and Kyoto Encyclopedia of Genes And Genomes pathways enriched by the DEGs were analyzed using DAVID. The obtained matrix was analyzed by weighed gene coexpression network analysis. A total of 350 significant DEGs were identified through differential analysis, and these DEGs were significantly enriched in functions associated with keratinization, and the pathway of neuroactive ligand-receptor interaction. Moreover, 72 hub genes were identified through weighed gene coexpression network analysis. After the hub genes and DEGs were combined, we obtained 422 union genes, including 65 survival-associated genes. After regression analysis, a HPV-related prognostic model was established, which consisted of 8 genes, including Clorf105, CGA, CHRNA2, CRIP3, CTAG2, ENPP6, NEFH, and RNF212. The obtained regression model could be expressed by an equation as follows: risk score = 0.065 × Clorf105 + 0.012 × CGA + 0.01 × CHRNA2 + 0.047 × CRIP3 + 0.043 × CTAG2-0.034 × ENPP6 - 0.003 × NEFH - 0.068 × RNF212. CGA interacted with 3 drugs, and CHRNA2 interacted with 11 drugs. We have identified an 8 HPV-RNA signature associated with the prognosis of SCCHN patients. Such prognostic model might serve as possible candidate biomarker and therapeutic target for SCCHN.

RESUMO

Currently, a standardized design and calculation specification for suction drum foundations has yet to exist in China. The engineering design currently depends mainly on the subjective understanding and engineering experience of the designers, which can be considered somewhat blind and subjective. In this paper, we utilize the offshore wind power project in Yangjiang City, Guangdong Province, as our case study. Building upon domestic and international research results, relevant investigations, design specifications, and engineering applications in related fields, we conduct a systematic study on the design calculation and construction control technology of the suction drum foundation. The document presents the design calculation and inspection of the suction drum foundation. Building on this foundation, we propose a sinking feasibility analysis method and a parameter value method for the suction drum foundation calculation. We also examine the suction drum foundation construction process, examining its control parameters, technology, and standards. Finally, based on the measured data from six four-barrel guided frame platform suction drum foundations that were successfully installed, the proposed design and control method are evaluated, and their effectiveness is verified. The results of this study can provide valuable references for the design and construction of similar suction drum foundation platforms.

RESUMO

BACKGROUND: Anastatus japonicus Ashmead, a biological control agent utilized in China to control fruit bugs and forest caterpillars, is efficiently raised on large Chinese oak silkworm (Antheraea pernyi) eggs. Here, we investigated the biological parameters of non-diapaused and diapaused Anastatus japonicus after long-term storage within eggs of the host, Antheraea pernyi, under laboratory conditions. RESULTS: Diapaused mature larvae of Anastatus japonicus were more cold-tolerant than non-diapaused mature larvae, as reflected by a lower supercoiling point, lower freezing point, and higher survival rate at cold temperatures. Diapause induction enhanced the lifespan, fecundity and oviposition period of Anastatus japonicus than non-diapaused Anastatus japonicus when refrigerated for 6 months. However, after 12 months of refrigeration, the fecundity and oviposition period of Anastatus japonicus were significantly reduced with and without diapause. No difference in the progeny sex ratio of Anastatus japonicus was observed between diapause-induction treatment and those of non-diapaused. With the extension of refrigeration period from 6 months to 12 months, the lifespan, fecundity and oviposition period of Anastatus japonicus which were treated with diapause induction showed a sharp decrease. No significantly difference in the lifespan, fecundity and oviposition period of Anastatus japonicus was observed between diapause-induction treatment and those of non-diapaused when refrigerated for 12 months. CONCLUSION: These results suggest that the induction of diapause is an applicable technique to achieve mass production of Anastatus japonicus in long-term storage using eggs of the factitious host Antheraea pernyi, without compromising the quality of the parasitoid. The refrigeration period of diapaused Anastatus japonicus should not exceed 6 months. © 2023 Society of Chemical Industry.

RESUMO

ObjectiveTo investigate the change and potential role of Mindin protein in the treatment of chronic hepatitis B (CHB) with PEG-IFNα-2b. MethodsA total of 29 CHB patients who received the treatment with PEG-IFNα-2b in The Second Affiliated Hospital of Xi’an Jiaotong University from January 2018 to December 2019 were enrolled, and according to their clinical outcome, they were divided into cured group with 17 patients and uncured group with 12 patients. Peripheral blood samples were collected from both groups at baseline, 12 weeks, and 24 weeks to measure blood routine indices, liver function parameters, hepatitis B markers, and Mindin protein. HBsAg, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and Mindin protein at different time points were compared between the two groups. The independent-samples t test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; a Spearman correlation analysis was used to investigate correlation; a multiple linear regression analysis was used to investigate the influence of HBsAg and ALT on the content of Mindin protein. ResultsThe analysis of baseline data showed that there were significant differences in the levels of HBsAg, HBeAb, albumin, and albumin/globulin ratio between the cured group and the uncured group (all P<0.05). The cured group tended to have a gradual increase in the level of Mindin, and the level of Mindin at 24 weeks was significantly higher than that at baseline (P<0.05). The cured group had a significantly higher level of Mindin protein than the uncured group at 24 weeks (P=0.019). The cured group had a significantly lower level of HBsAg than the uncured group (P<0.05), with a significant change from baseline to each time point within the cured group (P<0.05). In addition, the levels of ALT and AST in the cured group tended to first increase and then decrease, and the expression levels at 12 weeks were significantly higher than those at baseline (P<0.05). At 12 weeks, there was a strong linear correlation between Mindin protein levels and ALT in the untreated group (r=0.760 8, P<0.05), and further multiple linear regression analysis also demonstrated a linear relationship between the two (b=1.571, P=0.019). ConclusionThere is a significant difference in the level of Mindin protein between the cured group and the non-cured group after 24 weeks of PEG-IFNα-2b antiviral treatment, and therefore, detecting the dynamic changes of Mindin protein can better predict the treatment outcome of CHB, which provides a reference for clinical practice.

RESUMO

Given the significant therapeutic efficacy of anti-HER-2 treatment, the HER-2 status is a crucial piece of information that must be obtained in breast cancer patients. Currently, as per guidelines, HER-2 status is typically acquired from breast tissue of patients. However, there is growing interest in obtaining HER-2 status from serum and other samples due to the convenience and potential for dynamic monitoring. In this study, we have developed a serum Raman spectroscopy technique that allows for the rapid acquisition of HER-2 status in a convenient manner. The established HER-2 negative and positive classification model achieved an area under the curve of 0.8334. To further validate the reliability of our method, we replicated the process using immunohistochemistry and in situ hybridization. The results demonstrate that serum Raman spectroscopy, coupled with artificial intelligence algorithms, is an effective technical approach for obtaining HER-2 status.

RESUMO

Temperature sensitivity (Q10) of soil organic carbon (SOC) decomposition is an important index to estimate the dynamics of soil C budget. However, the spatial variation of Q10 and its influencing factors remain largely uncertain. In this study, we reviewed the effects of climate environment, spatial geographic pattern, soil physicochemical property, vegetation type, microbial community composition and function, and global climate change on Q10 to summarize the general rule of each factor influencing Q10 and compare the relative contribution of each factor to Q10 in different ecosystems. The results showed that Q10 decreases with the increases of temperature and precipitation, but increases with the rise of latitude and altitude. The Q10 value is higher in grassland than that in forest, and also in coniferous forest and deciduous forest than that in evergreen broad-leaved forest. Carbon quality is negatively correlated with Q10, but the C quality hypothesis is not always valid with exogenous substrate input. For example, the increment of substrate availability may significantly increase Q10 in low-quality soils. Q10 decreases with the enhanced proportion of r-strategy microorganisms (Proteobacteria and Ascomycetes), but increases with the enhanced proportion of K-strategy microorganisms (Acidobacteria and Basidiomycetes). Q10 increases with elevated CO2 concentration, but declines with atmospheric nitrogen deposition. In natural ecosystems, Q10 is mainly regulated by temperature and C quality. Temperature is the main factor regulating Q10 in the topsoil while C quality is the main factor in deep soil. Our review provided a theoretical support to improve the coupled climate-C cycle model and achieved the C neutral strategy under global warming.

RESUMO

OBJECTIVE: To investigate the efficacy of electroacupuncture (EA) stimulating Zusanli (ST36) and Xuanzhong (GB39) on synovial angiogenesis in rats with adjuvant arthritis (AA). METHODS: AA models were established by bilateral injection of Freund's complete adjuvant (FCA) in male Sprague-Dawley rats. Three days after injection, rats were given EA at Zusanli (ST36) and Xuanzhong (GB39) acupoints, once every other day, for 16 d. The arthritis index score, paw volume, and hematoxylin-eosin (HE) staining was performed for each animal. Angiogenesis marker cluster of differentiation 34 (CD34) expression and synovial cell apoptosis in synovial tissue were observed. The levels of Notch1, hairy and enhancer of split homolog-1 (Hes1), transforming growth factor-beta (TGF-ß) and basic fibroblast growth factor (bFGF) were subsequently detected. RESULTS: We found that EA significantly decreased arthritis index scores, paw volume, and HE staining scores. EA could significantly inhibit the expression of CD34, promoting apoptosis of synovial cells in the joint synovial tissue of AA rats. The expression of Notch1 signaling pathway proteins and mRNAs (Notch1, Hes1, TGF-ß, and bFGF) were markedly downregulated by EA treatment. CONCLUSIONS: These results prove that EA attenuates synovial angiogenesis by inhibiting the Notch1 signaling pathway in AA rat models. Based on our findings, we propose that EA is a promising complementary and alternative therapy in rheumatoid arthritis.

RESUMO

OBJECTIVE: The aim of this study was to investigate the protective effects of Tuina (a traditional Chinese massage therapy) on intervertebral disc (IVD) degeneration and the regulatory mechanisms of the transforming growth factor-ß1 (TGF-ß1)/small mothers against decapentaplegic (Smad) signaling pathway. METHODS: Thirty New Zealand white rabbits were randomized into five groups: the control group, model group, model + Tuina group (Tuina group), model + TGF-ß1 group (TGF-ß1 group), and model + TGF-ß1 inhibitor SB431542 group (SB431542 group). The model was established by posterolateral annulus fibrosus puncturing (AFP). Recombinant TGF-ß1 and inhibitor SB431542 was injected into the TGF-ß1 group and SB431542 group with a microsyringe, respectively. The rabbits in the Tuina group received Tuina treatment along the bladder meridian for 4 weeks. Magnetic resonance imaging (MRI) was performed on rabbits before AFP and after 4 weeks of intervention. Lumbar IVDs (L2-L3 to L4-L5) were harvested after intervention. Histopathological changes in the IVDs were measured by hematoxylin and eosin (HE) staining. Type I collagen was analyzed by immunohistochemistry detection. The expression level of matrix metalloproteinase-3 (MMP3) was determined by enzyme-linked immunosorbent assay. Cell apoptosis was evaluated by terminal deoxynucleotidyl transferase-mediated nick end labeling and Western blotting. Real-time polymerase chain reaction and Western blotting were used to analyze the expression of TGF-ß1 and Smad2/3/4 and a disintegrin and metalloproteinase with thrombospondin motifs 5. RESULTS: Posterolateral AFP induced IVD degeneration in rabbits with histopathological damage and noticeable changes in MRI images. Tuina alleviated histo-pathological changes and reversed the expression of extracellular matrix degeneration-related molecules and apoptosis-related proteins. Furthermore, AFP induced the activation of TGF-ß1 and Smad2/3/4, whereas Tuina therapy markedly reduced the protein expression of Smad2/3 and the gene expression of TGF-ß1 and Smad2/3/4. Additionally, the TGF-ß1/Smad signaling pathway was activated in the TGF-ß1 group, while the TGF-ß1/Smad signaling pathway was inhibited in the SB431542 group. CONCLUSION: Posterolateral AFP induced disc degeneration as determined by MRI assessment and histological analysis. Tuina alleviated disc degeneration, possibly by inhibiting the fibrotic response mediated by the TGF-ß1/Smad pathway, thus alleviating extracellular matrix degeneration and reducing cell apoptosis.

RESUMO

It is rare for one fluorophore scaffold to harbor both positive and negative solvatochromism. Herein, we tailor chalcone analogues to achieve both positive- and negative-polarity sensitivity of fluorescence intensity. We explore two chalcones of opposite solvatochromism to simultaneously detect the co-aggregation of wild-type and mutant superoxide dismutase that cause amyotrophic lateral sclerosis disease.

RESUMO

BACKGROUND: Anlotinib is used as a third-line treatment for advanced non-small-cell lung cancer (NSCLC), but has limited clinical benefits and several side effects, such as diarrhea and acneiform skin rash. Traditional Chinese Medicine (TCM) is commonly used to treat cancers in China. Chinese herbal medicines may have the potential as adjuvant therapies to reduce toxicity and improve the efficacy of treatments for NSCLC. Given the positive outcomes of basic research, we plan to evaluate whether the addition of the Chinese herbal medicine Yifei Sanjie formula (YFSJF) to anlotinib can improve the progression-free survival (PFS) of advanced NSCLC patients. METHODS: A multicenter, randomized, double-blind, placebo-controlled parallel-group controlled pilot trial will be performed. Forty eligible patients will be randomized in a ratio of 1:1 to the intervention (YFSJF + anlotinib) and control (placebo + anlotinib) groups. Participants will be advised to take 12 mg/day of anlotinib on days 1 to 14 of each 21-day cycle. YFSJF or placebo will be administered (15 g twice daily) during each cycle until progression of disease (PD). The primary outcome will be progression-free survival (PFS), and the secondary outcomes will be overall survival (OS), the objective response rate (ORR), and patient-reported outcomes (PRO). Tumors will be assessed based on RECIST v. 1.1 after every 2 cycles of treatment. The M. D. Anderson Symptom Inventory-Lung Cancer (MDASI-LC) will be used to evaluate PRO at baseline and weekly thereafter until PD. DISCUSSION: This will be the first trial to evaluate the effectiveness and safety of TCM combined with anlotinib for the treatment of NSCLC. The results of this randomized controlled trial will fill a gap in the research by showing whether YFSJF combined with anlotinib can improve PFS in NSCLC patients. TRIAL REGISTRATION: The study was registered on June 8th, 2021 on Chinese Clinical Registry; registration number ChiCTR2100047143. (https://www.chictr.org.cn/index.aspx). ETHICS AND DISSEMINATION: The Ethics Committee of the First Affiliated Hospital of Guangzhou University of Traditional Chinese Medicine approved the study protocol (approval no.: K2020151, 2021/08/19). The study will also be supervised and managed by the Ethics Committee.

RESUMO

BACKGROUND: Stroke leads to severe difficulties in daily activities, even when performing a simple task, such as walking from one point to another. The first apparent compensatory strategy in stroke survivors during walking is to slow down the walking speed. Slowing down the walking speed directly reduces the step length and cadence and further increases the stance phase, double, and support time. These alterations are to develop a compensatory strategy; however, this strategy generally leads to joint injuries and increases the potential risks of falls. RESEARCH QUESTION: A review strongly suggests that walking on the inclines may enhance this compensatory strategy. Therefore, this study attempted to extend the current knowledge to understand the fundamental gait control in patients with acute stroke during walking on inclines. RESULTS: These results showed that (1) compared to healthy control, patients with acute stroke demonstrated different gait controls during walking on inclines, (2) the gait performance was enhanced when stroke patients were instructed on different inclines, and (3) the asymmetric gait pattern was reduced by walking on inclines. SIGNIFICANCE: This study concluded that walking on inclines enhances gait performance (greater spatial but smaller temporal gait characteristics) and reduces spatial gait asymmetry.

RESUMO

Benzodiazepines(BDZs)are used in clinics for anxiolysis,anticonvulsants,sedative hypnosis,and muscle relaxation.They have high consumptions worldwide because of their easy availability and potential addiction.They are often used for suicide or criminal practices such as abduction and drug-facilitated sexual assault.The pharmacological effects of using small doses of BDZs and their detections from complex biological matrices are challenging.Efficient pretreatment methods followed by accurate and sensitive detections are necessary.Herein,pretreatment methods for the extraction,enrichment,and preconcentration of BDZs as well as the strategies for their screening,identification,and quantitation developed in the past five years have been reviewed.Moreover,recent advances in various methods are summarized.Characteristics and advantages of each method are encompassed.Future directions of the pretreatment and detection methods for BDZs are also reviewed.

Objective:To explore the effect of health education based on symptom management strategy on the psychological status, self-management ability and quality of life of maintenance hemodialysis patients.Methods:A randomized controlled trial method was used. One hundred and fifty hemodialysis maintenance patients in the Blood Purification Center, Jinan People's Hospital from August 2019 to August 2020, were selected as the research subjects by convenience sampling. Patients were divided into a control group and observation group by random number table method, with 75 cases in each group. The control group was given routine health education, and the observation group was given health education based on symptom management strategies. Self-rating Anxiety Scale (SAS), self-rating Depression Scale (SDS), self-management ability scale of dialysis patients, and SF-36 quality of life scale were used to compare the improvement of negative emotion, self-management ability, and quality of life in the two groups.Results:There was no statistically significant difference between the control group and the observation group before the intervention (all P>0.05). After 3 months of intervention, the SAS and SDS scores of the patients in the observation group were (36.42 ± 4.09) and (35.74 ± 3.64) respectively, which were lower than those of the control group (46.37 ± 4.64) and (49.38 ± 2.49). The difference was statistically significant ( t=8.46, 9.42, P<0.05); the self-management score of patients in the observation group (80.11 ± 7.83) was higher than that in the control group (47.21 ± 6.62), with a statistically significant difference ( t=32.29, P<0.05); the total score of SF-36 quality of life in the observation group (594.32 ± 35.03) was higher than that in the control group (501.42 ± 32.78),with a statistically significant difference ( t=24.66, P<0.05). Conclusions:Health education based on symptom management strategy can improve the psychological status of maintenance hemodialysis patients, and has important value in improving their self-management ability and quality of life.
